B&K Precision 190xB Switching DC Power Supplies

B&K Precision 190xB models are laboratory-grade switching mode DC power supplies. These have high current output in a small form factor and lightweight package. The DC power supplies provide various configurations of high output voltage or high output current. These power supplies make setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control. The DC power supplies offer constant voltage (CV), constant current (CC), preset, and remote control modes. These save up to three different presets of voltage and current values for quick recall. A remote sensing terminal (model 1900B only) is also available to compensate for long output line losses. The applications include production testing, telecommunications, R&D, service, and university labs.
